<h2>HDR TIFF File format</h2>

<p>Here you can choose which TIFF-HDR format Luminance HDR will use to save an HDR image.</p>

<p>LogLuv TIFF is the appropriate format for most cases because it stores the hdr data in a reasonable amount of space (i.e. file size). Even if it is a 16 bit format, it can store floating point data.</p>

<p>The Float TIFF format has to be used only if you want to load your tiff in another application that cannot open the LogLuv format.</p>

<h2>HDR Visualization</h2>

<p>Click on the buttons to pop-up a window that lets you choose which color to use for the nan/inf and for the negative values.
